Long legged spikey

Starting to make a spikey on long legs, may fill with powder. May cover with paper pulp rather than plaster to keep lighter

Spikey silicone lining

The T30 silicone recommended by Tiranti proved very tricky to paint on the inside of the spikey. The Thixo additive turned it into a clump of coagulated custard and wasted a whole 1kg tin. Tried again using tiny quantities as even then the time it remained paintable was tiny. The surface is lumpy so thinking before I start another tin. Maybe I should try another type that is easier to paint.
